[ Method ] Control effects of five insecticides against C. lataniae were studied through indoor bioassay and field trial. [ Result] Bioassay results showed that the indoor toxieities of 10% ct-cyper- methrin, 22% sulfoxaflor and 10% imidecloprid were higher, with LC50 of 15.28, 30.00 and 30.23 rag/L, respectively. In field trials, the control effects of 10% α-cypermethrin, 22% sulfoxaflor and 10% imidacloprid against C. lataniae were over 90% for all the concentrations at 10 d post adminstration. The control effect of 22% sulfoxaflor reached 100% for all the concentrations at 5 d post administration. [ Conclusion] 10% α-cypermethrin was a superior pesticide against C. /a- taniae, but 22% sulfoxaflor and 10% imidaclopfid were more efficient in emergency.展开更多
